Frequently Asked Questions
What is the voltage and wattage rating of this diode?
The diode carries the intake designation 3.48V.4W-ZD, denoting a 3.48-volt nominal breakdown voltage and a 0.4-watt (400 mW) power dissipation rating.
What are the physical dimensions?
The cylindrical body measures 4 mm in length with standard axial leads for through-hole PCB or point-to-point wiring.
Why purchase an individual diode instead of a bulk assortment?
Buying an individual verified component gives you the exact voltage rating needed for a repair without paying for an assortment of unneeded values. Orders leave our Idaho warehouse the same or next business day with $8 flat rate shipping, or free shipping on orders over $28.
Some repair jobs stall out for want of a single oddball reference voltage that modern parts bins forgot. This little glass diode steps into the circuit to lock the rail down exactly where the original design intended.
